To all whom it may concern:

Be itknown that l, HENEY Knannnno, a citizen of the United States of America, and Y resident of Martins Ferry, county of Belmont, and State of Ohio, have invented certain new and useful Improvements in Gas Burners, of which the following is a speci: c fication. Q

This invention relates broadly to gas burners, and more specifically to a burner for iglil: stoves and ranges, hot plates, and the The primary object of the invention is to provide a simpleand durable gas burner for stoves, ranges and hot plates, which is "constructed wholly of \,sheet metal and which consequently, is comparatively inerpensive to manufacture.

in describing the invention in detail, reference is herein had to the accompanying drawings, in which Figure 1 is a top plan proved gas burner; v Figure 2 is a longitudinal section on line 2-2, Fig. 1;, v

Figure 3 is a cross sectionon line 3 3; Fig. l;

Figure l is an end elevation of the burner tube and damper; and- E Figure 5 is a view similar to Fig. 1.. illustrating a modification.

Referring to said drawings, the invention comprises a sheet metal shell or casing consisting of an outer. wall 1, preferably cylindrical'in form, and an inner tubular wall 2 located concentrically with respect to and at a suitably spaced distance from said wall 1. Said shell or basing is pressed View of my imfrom a single sheet metal blank and has a bottom 8 joining said walls 1 and 2. The lower end of the tubular wall 2 is preferabl y tapered, as shown. Closely fittedbetween the upper end portions of said walls 1 and 2 is a ring shaped cap a of sheet metal, the same being of shallow tl-shape in cross section and serving as a closure for the top of said casing.

A multiplicity of small passages 5 of approximately semi-cylindrical form is provided intermediate the wall L01? the shell and the therewith engaging wall of the cap 4}; and a plurality of similar passages 6 is provided intermediate the wall 2 of the shell and the therewith engaging wall or said cap, said passages 5' and 6 being formed by the provision in the upper portions or said walls 1 and 2 of vertically disposed crimps V l and 2 Saidpassages so arran ed con- 'stitute burner openings through w ich the gas admitted to the interior of the burner issues in the form of two concentric eircular rows of jets.

A mixing tube 7, opens into the interior of the casing having its inner end fitted within an opening provided therefor in the lower part or the wall 1 and being rigidly attached to said wall, as by electric weldin Said tube is formed to two substantia y semi-- cylindrical sections which are permanently attached oneto the other, one of said sections having its lateral edges turned outward to form flanges 8 and the other section having hook-like flanges 9 turned into embracing or clamping relation to said flanges 8. An

apertured disk 10 is rigidly carried upon the outer end or the mixing tube, having an annular flange l0 turned into closely embracing relation to a flange i formed on the tube. Said disk has therein a central opening ill for the reception of the end of an ordinary gas supply nozzle (not shown),

and an inwardly pressed collar 12 is formed about said opening for embracing said nozale. A dish 13 which is apertured to a proximate the form oi the dish 10 is mounted for rotation on said collar 12 and has its outer edge received between said disk 10 and the flange 7 of thelmixing tube. Said dish 13 is adapted for rotary movement with respect to the disk 10 to position its apertures 14 relative to the apertures 15 of dish 10 to regulate the air supplied for mixing with the gas. A rejecting finger piece 17 carried by said disk 13 provides means whereby the latter may be grwped for eidecting notation Additional air for promoting combustion of the gas which issues from the two rows till forward the inflowing gas to the extent that the latter isprevented froml' rising and issuing in preceptibly greater volume from the passages nearest the side at which it 6 enters than at other points.

In the modification illustrated in Fig. 5.

the upright walls of the cap 4 have formed therein crimps similar in form to and adapted to register with'the crimps 1 and 2 of the shell, thereby forming passages 5 and 6 ofapproximately cylindrical form:

I 4 The burner described is not only simple in form and comparatively inexpensive to construct, but is also effic1ent 1n OPBIMJIOII and possesses great durability.

What is claimed is-- 1. In a gas burner, a casing .comprising two substantially cylindrical upright concentrically related walls having an intermediate closed bottom, a ring-like closure fitted between'the upper ends of said walls, said walls having their closure engaging surfacrs provided with crimps whereby are formed between said walls and said closure concentrically related rows of ports for egress of gas from the casing, and a mixing tube opening into said casing for supply- "ing gas into the latter.

2. In a gas burner, a one-piece casing comprising an outer substantially cylindrical upright wall, an inner upright tubular wall, said walls being concentrically related, and a bottom intermediate the lower ends of said walls; a ring-like closure fitted between the upper ends of said casing walls, said Walls and said closure being shaped relatively to form therebetweentwo concentrically related rows of ports for egress of gas from the interior of the casing, and means for conducting gas to the interior of the casini 3. gas burner COIIIPI'ISIDg a one-piece casing shaped to form two substantially circular concentrically related upright walls with an intermediate closedbottom said walls having'vertical crimps formed in the upper end portion thereof, a ring-like closure fitted between said walls, said closure having upright flanges on its outer and inner edges seated against the crimped surfaces of said walls and complementing the latter 1n the formation of two concentric rows of.

ports for egress of gas from the interior of thecasing, and means for conducting gas to the interior of the casing.

4. A gas burner comprising a one piece casing shaped to form two substantially circular concentrically related upright walls with an intermediateclosed bottom, a ringlike closure disposed between said walls and having inner and outer edge flanges seated against said walls, said walls and said flanges being shaped relatively to provide therebetween ports for egress of gas from the interior otsaidj casing, at least one of said engaging surfaces having crimps formed thereln. s

5. A gas burner comprising a one piece casing shaprd to form two substantially circular concentrically related upright walls with an intermediate closed bottom, a ringlike closure disposed between said Walls and Witnesses:
